IllegalArgumentException: sockaddrToInetAddress unsupported ss_family: 0

See original GitHub issue

I’ve been seeing this exception in a couple of my users’ crash logs. I haven’t really been able to replicate it either. The crash occurred on OkHttp 3.7.0, on Android 7.0, on a Samsung Galaxy S8+. Unfortunately, I don’t have much other information that I can provide, since I haven’t been able to personally recreate this crash.
